January Meeting Recap

Dr. Charles S. Tritt, Ph.D, from MSOE, did a presentation on Human-Human Interface, using a TENS (Transcutaneous electrical nerve stimulation) unit and simulation electrodes. Taken from his document:

This device mimics a relatively common approach to controlling powered prosthetic limbs. Electromyogram signals are picked up from the surface of the skin, amplified, digitized, processed and used to effect the desired control. In this case, the control is via nerve stimulation using a TENS unit.

The ZIP file containing his handout from the meeting (which has the parts list), MSOE lab handouts, and Matlab and Arduino code, can be found here

The total cost of the build is $98

We have some media of the device being used. More will be posted as it is processed. If you have media, videos, or pictures, that’d you’d like to share, please let me know.

Korgo and Belouve presented on the upcoming Cyphercon. DC414 can still get in, though it seems most of DC414 are already attending or volunteering. If you still want to get in, contact Korgo or Belouve.

There will be a booth/space for DC414 and Milwaukee Hackers (basically anyone I recognize as a Milwaukee area hacker) at the Friday part of the convention. We’ll keep it a corporate no-fly zone.

We got a peek at one of the electronic badges for Cyphercon.

Puzzle Lock

Belouve brought a puzzle lock that he received from India. It is claimed to be from the era of Shivaji Maharaj, who reigned from 1674 to 1680. I’m investigating this claim to its age further. Regardless, it’s a cool lock.

I have no video or images for my lock (yet), but I plan to make a video in English of its function and any more details I can find out. However, I found a video of a similar lock here
